2. How does Nourishing Biologicals work?

Nourishing Biologicals is based on the idea of Miracular Cellular Communication™, a profound discovery that allows our ingredients to repair defects at the deepest level, through intelligent and bio-dynamic communication with the cells. Essentially, Miracular Cellular Communication™ is how our skin aids in repair or resists damage.

If you’d like to keep your largest and most visible organ (your skin) healthy, our products are for you. They were specifically formulated for people from all walks of life with all skin types who wish to restore their confidence and improve their overall health.


4. What ingredients can be found in your products?

All of our ingredients are pharmaceutical grade, the highest grade of purity available and are therefore free of contaminants. Also, all of our growth factors are bioidentical, meaning that they are identical to what is naturally present in our bodies.

Additionally, our active growth factors are tested by CellTiter-Glo® Luminescent Cell Viability Assay for activity verification. Other ingredients are organically sourced and free of parabens.


5. Where is your product line formulated?

Our products are proudly made in the USA (Arizona) while our fulfillment is also done in the USA (Iowa) and are headquarters in St. Augustine, Florida.


6. Are your products safe?

Yes! Our products are very safe and effective. In fact, 200 clinical trial participants showed no sensitivities, proving that they are gentle enough for even the most sensitive skin.


7. How long does it take to get results?

Most people enjoy noticeable results after one use and optimal results within 30 days. Since the key to achieving great results with our products is consistency, be sure to use them every morning and evening.


8. Are your products organic?

Although our products are mostly organic, some are not available in organic form. Rest assured they are cruelty free and use the purest ingredients as well as bio-identical growth factors.


9. Who founded Nourishing Biologicals?

Our products were developed by Dr. George Sadowski, a renowned surgeon. After his 25 year surgery career, he searched for fulfillment and brought Nourishing Biologicals to life. Dr. George performed a great deal of research and testing and made groundbreaking discoveries that led him to develop the most powerful skincare products to ever exist.


10. What is the NB Skin Institute?

Our NB Skin Institute is our educational destination supported by Dr. George Sadowski, Medical Research Esthetician, Grace Latuberza, and Director of Aesthetics, Natalia Sadowski. We provide state-of-the-art training for skin care professionals in the most technologically advanced non-invasive procedures such as Plasma Fibroblast Lift, and Scar Camouflage.


11. How do your products treat the cause, not the symptom of skin damage?

We use antioxidants and anti inflammatories to decrease inflammation and stop damage at the deepest level. Our products allow the skin to renew its function and restore its health so you can look and feel your best.


12. What makes your products so effective?

Unlike other skincare products on the market, Nourishing Biologicals has the power to repair and nourish the skin from the inside out. Our products are carefully formulated with Nobel Prize-winning growth factors and bio-natural proteins that match those of the human body. They defend and reverse the signs of skin aging at the deepest level and before skin damage becomes visible to the naked-eye.


13. What are Nobel-Prize winning growth factors?

In 1986, American biochemist, Stanley Cohen and Italian developmental biologist, Rita Levy Montalcini were awarded a Nobel prize for discovering a growth factor known as the epidermal growth factor that could grow cells. Throughout the years, the technology has advanced significantly so we now use small active peptides that achieve the same activity that growth factors were able to in the past.


14. How can I stay up to date on your latest products and promotions?

Once you subscribe to our newsletter, you’ll receive regular updates on our offerings as well as useful health and wellness tips.


15. Why do Nourishing Biologicals products have an expiration date? Is it okay to use them past the expiration date?

NB skincare systems are created using best and purest globally sourced ingredients and formulated to treat your skin from the inside out. Our skincare solutions are crafted with natural ingredients, botanicals, and Nobel Prize-winning growth factor technology, so we stamp a best-if-used-by date on each product. However, our product tests indicate that they remain effective for 60 days beyond the expiration date. We offer a 100% money-back guarantee, so if you prefer an exchange, please contact us and we will send you an updated product.
